Implementing Detect and Respond functions in NIST CSF

This article provides pragmatic guidance for UK SMEs on implementing the Detect and Respond functions of the NIST Cybersecurity Framework, focusing on prioritising telemetry (identity, endpoint, email, cloud, admin logs), designing detection use-cases mapped to MITRE ATT&CK, building realistic response playbooks, tuning detections to reduce false positives, and measuring effectiveness with metrics like time-to-detect and time-to-contain.
